Factual error: When it's 00:00 on January 1st, it's not night in Sydney, it's 11 AM. When they 'reveal' stuff at the end of the movie, and they show that things happen exactly at 00:00 in the night in London, it can't possibly be dark in Sydney, Australia.
Suggested correction: It shows that Sydney is at dusk and is becoming dark, so around 5pm-6pm-ish, not 11am during the day.
Factual error: Throughout the movie, all sorts of messages are passed over the 1MC (ship's intercom) when the boat is supposed to be stealthy. They've set "Ultra Quiet" to avoid the enemy sub but no-one was any quieter, and everyone was still using the 1MC. Worse, people are shouting commands and status updates, both in person, and over the intercom! No wonder that Akula found them. The only thing protecting this ship was plot armor! In real life, messages would be passed quietly using sound powered phones (which we also see), rather than blasting the info loudly to the entire crew, because sonar will literally pick up the sounds of loudspeakers and people shouting. Let's not even mention classified target data being passed to the entire ship's crew on the 1MC. (00:49:00)
Factual error: Aquaman lifts a submerged submarine towards the surface, which should start to sink again straight after releasing it, as its ballast tanks are still full of water. It shouldn't stay floating like that.
Factual error: On the bus ride in Nepal, they're playing a Hindi song from an Indian movie (Kabhi Khushiyan Kabhi Gham) that was released in 2001. The time frame on the bus is 1996.
Factual error: In the balloon scene, it seems like Q can circle around and land on a spot where he flew past previously. A balloon can only fly in the direction of the wind.
Factual error: Throughout the "Manhattan" race scenes, it is obvious that the location is nowhere near New York. The wide two-way streets, west coast-style traffic signals, street furniture, and architecture look nothing like Manhattan.
Factual error: Dora picks up the solid gold statue - by the size it would weigh in excess of 500 lbs. She then lifts it up and places it back on the mantle above her head. A grown man could not do that, let alone a child. (01:31:06)
Factual error: It's mentioned that the British and New Zealanders turned the Americans away. This is untrue - the Americans stayed with both for a time until it was decided that they would be safer with the Canadians.
Factual error: How would the creature be able to re-enter the ship by climbing into the reactor piping? The reactor fuel system is not open to the living space of the International Space Station.
Factual error: Jack Ryan takes the enlisted oath, not the officer's oath, when commissioned into the Marines. (00:02:35)
Factual error: The movie and events take place in 1958. However, two Fender amplifiers that are used by the band, "Johnny Casino and The Gamblers" are "Silverface" models that were only manufactured between 1967 and 1981.
Factual error: Dexter the capuchin is in the African mammal display. Capuchins come from South America.
Factual error: When the house explodes, there is a massive explosion and fireball that creates a pressure wave strong enough to send Brian flying into the van. However, not a single window breaks on the houses just feet from the explosion. (00:15:40)
Factual error: There's no way that the knife that killed Bob was long enough to go through his body and impale the wall behind him. And a butcher knife cannot "pin" a human body to a wall and just stay put, they aren't strong enough.
Factual error: The Pentagon is the largest office building in the world. It has seven floors, 28 kilometers of corridors and 620,000 square metres of office floor space. The idea that the entire building could be searched in one afternoon by six people is beyond absurd. If those six people could search an average of one office every five minutes and they worked twenty four hours a day, seven days a week they'd get through the whole building in 89 days and 15 hours. I don't think the punter they are looking for has a lot to worry about.
Factual error: There is no way a 2001 phone's tiny speaker could be heard a hundred meters away in the belly of a dinosaur or later buried in a mound of dino dung.
Factual error: During the first battle with an Anaconda, the 55-gallon fuel drums lashed to the deck of the riverboat are swept over the side, where they sink to the bottom of the river. This plot device drives the rest of the movie, since the boat must make a dangerous detour through "Anaconda country." There is just one small problem with this: Fuel drums full of diesel fuel or gasoline float on water. The fuel in them makes them buoyant. It would have been a simple matter for someone to get a rope or a boathook and retrieve the fuel drums before they floated away.
Factual error: When Trinity is being arrested, you hear the cops all burst into the room and cock the hammers on their Glocks. The Glock doesn't have an external hammer. To load the weapon, you have to pull the slide back and release it. (00:01:50)
Factual error: The lady hacked a tablet with he command mkdir -p on the command prompt. mkdir command is used to make a folder. (01:00:00)
Factual error: Gabriel kills the engineer and sets the train to full speed, then locks the control room. Without the engine being resupplied with coal it would lose power and stop before too long, never getting as far as the bridge.
Suggested correction: It is known for firemen to fill the loco up to allow it to run for 15-20 minutes without new coal. However, it could not run that long at that speed without the boiler being refilled with water, so the boiler would have exploded well before the fire reduced.
